Add the remaining fp_round libcalls:
FPROUND_F80_F32, FPROUND_PPCF128_F32,
FPROUND_F80_F64, FPROUND_PPCF128_F64
Support for soften float fp_round operands is added, Mips
needs this to round f64->f32.
Also added support to soften float FABS result, Mips doesn't
support double fabs results while in 'single float only' mode.
